It was one of those moments where you don’t quite believe what you’ve just heard.

People in the queue behind me were laughing. I’m not sure if they thought she was being funny or were as shocked about what she was saying as I was.

It was so odd. I have never met this woman. I don’t mind the normal questions about my bump as it’s very visible, but this was just unprofessional and rude.

She was basically implying that I was a slag because I was pregnant. She doesn’t know anything about me.

She took one look at my bump and said: ‘Nothing on TV that day?” At first I was too shocked to speak or make eye contact.

As she packed her items into a bag, Emily said the employee continued to make inappropriate remarks.

She then asked Emily if she needed cashback, before quipping: ‘You won’t be able to afford cash back once it’s here anyway.’ (Picture: Mercury)

The Lidl store, in London Road, only opened seven weeks ago, and Emily said she would be reluctant to return after her experience on Sunday afternoon.

Emily, who married 44-year-old Craig last June, said: “I though it might be mistaken identity and the woman thought she knew me but I just kept quiet thinking she would shut up.’

Emily, who doesn’t know the baby’s gender, is due to give birth on February 2.

She and Craig had been trying to conceive naturally for two years before turning to IVF in December 2014, and underwent treatment in April and May last year.

A Lidl spokesperson said: ‘We expect the highest standard of customer service from all of our employees and were very sorry to learn of this incident.

‘We are investigating it as a matter of priority and will be taking the appropriate steps. As a matter of course we will ensure that employees of our Wellingborough store receive additional training, to avoid anything like this from happening again.’
